According to franz bardon a magician is someone who practices magic with the appropriate magical training, and a sorcerer is someone who practices magic with little to no magical training. He also goes on to explain that sorcerers will fall prey to the demonic, use magic for only selfish purposes. While the magician does not fall prey to the temptations of the demonic can command all spirits, does not use magic for selfish reasons, and follows divine ordinance. But the training required to become a proper magician according to Bardon is so meticulus that we would all be considered sorcerers. But the definitioms vary according to cultures. Both use magic.
